Hi,

What values should you input into the target AFR table for a Supercharged engine. Approximate figures are explained in the courses for the understanding of AFR. My question is how to figure out this values for the specific engine. or they always an approximate? I have not seen anything about fine tuning this values.

thanks

Different engines will have different optimum ratios, even varying across the rpm and load ranges.

You haven't mentioned the fuel used, so actual AFR suggestions are not possible, but a lambda of 0.9 would be a good start point and you may find the engine responds better a little richer or leaner than that.

The reason is that the proper answer if found by testing and measuring the power output with a dyno.

Hi. thanks for the input. the fuel that will be used will be pump fuel 98 octane. unfortunately i will not be tuning on a dyno.
